Basalt Crushing Process Design

13/10/2023

Generally, the crushing process of basalt can adopt three-stage crushing process or four-stage crushing process.

Three-stage crushing process:

Basalt is an excellent aggregate of sand and gravel, and three-stage crushing process can reduce production cost.

For samll and medium-sacled basalt crushing production line, the crushing prcess usually adopts the process configuration of two-stage jaw 

cursher+impact crusher. Two stage jaw crusher can reduce the particle size of basalt to 60mm, and the third stage impact crusher will conduct 

shaping and crushing, so as to achieve the crushing effect of excellent particle size and low wear cost.

For large-sacled basalt crushing production line, the crushing process can adopt the process configuration of jaw crusher +cone crusher+impact 

crusher. The cone crusher can control the particle size of basalt to 50mm, and the third level impact crusher can conduct shaping and crushing. 

The power consumption and wear cost of cone crusher are relatively low, but the investment cost is relatively high.

Four-stage crushing process:

The basalt crushing machines in four-stage crushing process are jaw crusher, cone crusher, impact crusher (vertical shaft impact crusher), and the detail process is as following:

(1) Feeding: vibrating feeder.

(2) Coarse crushing: jaw crusher, feeding particle size is 1500-500mm, crushing to 400-125mm.

(3) Medium crushing: cone crusher or fine crushing jaw crusher, with feeding particle size of 400-125mm, crushing to 100-50mm.

(4) Fine crushing: impact crusher (or vertical shaft impact crusher), with feed particle size of 100-50mm, crushing to 32-5mm.

(5) Screening+ dust collecting: vibrating screen+ dry type dust collector.

(6) Shaping: impact crusher or vertical shaft impact crusher (after screening the fine crushed basalt, the qualified basalt particles will be sent to the storage bin through the belt conveyor. If the grain size and shape do not meet the requirements, the returned material will be returned to the impact crusher or vertical shaft impact crusher through the belt conveyor for further processing and reshaping).

(7) Screening+ dust collecting: vibrating screen+ dry type dust collector.

(8) Basalt transportation: belt conveyor.

(9) Control system: in order to reduce dust and soil, the coarse crushed stone is conveyed to the medium crushing cone crusher by the vibrating feeder, and the subsequent conveying between the stones is completed by the belt conveyor.
